RibbetMQ php扩展使用 实现队列生产消费

一般的队列系统，是指linux中的crontab定时启动脚本来处理任务:

首先下载一个rabbitmq的客户端，他相当于一个容器，装排队数据的容器

http://www.rabbitmq.com/download.html

默认的端口是55672   访问地址http://127.0.0.1:55672/

默认帐号密码   guest    guest

你可以看到rabbitmq 的管理界面

mq的任务是一个不浪费资源，的一个队列系统！

        php使用需要下载一个amqp扩展

         或者直接点击下面的地址找到适合自己的版本，下载

            http://pecl.php.net/package/amqp/1.2.0/windows

            rabbitmq.1.dll   放在C盘windows下

            php_amqp.dll    放入php扩展中

            开启php_amqp.dll的引用

            重启服务器

用phpinfo();

查看是否引用成功，如果出现以下的amqp扩展，那就说明成功了

首先是rabbitmq的生产者：

    创建第一个index文件：然后去mq中查看，如果添加一个test001的队列名信息，就说明已经添加进去了，xx22的信息已经在mq中存储！

    接下来就需要跑数据了。

    createQueue(array('xxx','2222'),'test001');

    echo "ok";

     function createQueue($message,$queueName,$exchangeName = '', $queueKey = '')

    {

        $queueName = self::getQueueName($queueName);

        $conn_args = array('host' =>'localhost', 'port'=> '5672',

            'login' =>'guest',        //mq帐号

            'password'=> '',        //mq密码

             'vhost' => '/');

        $conn = new AMQPConnection($conn_args);

        $conn->connect();

        $channel = new AMQPChannel($conn);

        if (!$exchangeName) {

            $exchangeName = $queueName;

        }

        $queueName = $queueName;

        if (!$queueKey) {

            $queueKey = $queueName;

        }

        $ex = new AMQPExchange($channel);

        $ex->setName($exchangeName);

        $ex->setType(AMQP_EX_TYPE_TOPIC);

        $ex->setFlags(AMQP_DURABLE); //exchange持久化

        $ex->declareExchange();

        $q = new AMQPQueue($channel);

        $q->setName($queueName);

        $q->setFlags(AMQP_DURABLE); //queue持久化

        $q->declareQueue();

        $q->bind($exchangeName, $queueKey);

        $channel->startTransaction();

        /**

         * 消息持久化,delivery_mode:2持久化、delivery_mode:1非持久化，其中priority是设置消息的优先级，测试中发现并未起作用。

         * 消息还有其他属性，请参考http://www.php.net/manual/zh/amqpexchange.publish.php

         */

        $result = $ex->publish(json_encode($message), $queueKey, AMQP_NOPARAM, array('delivery_mode'=>2, 'priority'=> 9));

        $channel->commitTransaction();

        $conn->disconnect();

    }  

有了生产者，那就有消费者。

脚本如果没有其他的修改或问题，基本上都是常年启动的：

消费者基类：

        class WorkerCommand{

        function qInit($q_name,$e_name='',$k_route=''){

                $q_name = Utils::getQueueName($q_name);

                $conn_args = array(

                    'host' => '127.0.0.1',            //mq的配置

                    'port' => '5672',

                    'login' => 'guest',

                    'password' => 'huoxingxing',

                    'vhost' => '/'

                );

        //创建连接和channel

                $conn = new AMQPConnection($conn_args);

                if (!$conn->connect()) {

                    die("Cannot connect to the broker!\n");

                }

                $channel = new AMQPChannel($conn);

        //创建交换机

                $ex = new AMQPExchange($channel);

                if (!$e_name) {

                    $e_name = $q_name;

                }

                $ex->setName($e_name);

                $ex->setType(AMQP_EX_TYPE_DIRECT); //direct类型

                $ex->setFlags(AMQP_DURABLE); //持久化

               // echo "Exchange Status:" . $ex->declareExchange() . "\n";

        //创建队列

                $q = new AMQPQueue($channel);

                $q->setName($q_name);

                $q->setFlags(AMQP_DURABLE); //持久化

               // echo "Message Total:" . $q->declareExchange() . "\n";

                if (!$k_route) {

                    $k_route = $q_name;

                }

        //绑定交换机与队列，并指定路由键

               // echo 'Queue Bind: ' . $q->declareQueue($e_name, $k_route) . "\n";

        //阻塞模式接收消息

                echo "Message:\n";

                while (True) {

                    $q->consume(array($this,'processMessage'));

                    //$q->consume('processMessage', AMQP_AUTOACK); //自动ACK应答

                }

                $conn->disconnect();

        }

}    

消费者：

class WorkerWareSyncBackUpCommand extends WorkerCommand {

    function actionIndex()

    {

        $this->qInit('SyncWareBackup');

    }

    function processMessage($envelope, $queue)

    {

        $msg = json_decode($envelope->getBody());

        Utils::doBackUp('back',$msg,'');

        $queue->ack($envelope->getDeliveryTag()); //手动发送ACK应答

    }

}
